GAS SEPARATION PROCESS

Fujifilm Manufacturing Eu...

1. A process for separating a feed gas comprising CO2 and non-polar gases into a gas mixture enriched in CO2 and a gas mixture depleted in CO2, the process comprising passing the feed gas through a gas separation unit comprising at least two gas-separation modules in order of decreasing selectivity for the CO2, wherein (i) the feed gas entering the gas separation unit comprises 1 to 35 mol % of CO2; (ii) each gas-separation module comprises a gas separation membrane; (iii) the feed gas is passed through a first set of gas-separation modules and then through a second set of gas-separation modules, wherein each of the gas-separation modules in the second set of gas-separation modules has a lower CO2 selectivity than all of the gas-separation modules in the first set of gas-separation modules; and (iv) all of the gas-separation modules in the second set of gas-separation modules comprise gas separation membranes having an ?CO2/CH4 selectivity of 5 to 25 and all of the gas-separation modules in the first set of gas-separation modules comprise gas separation membranes having an ?CO2/CH4 selectivity of 20 to 50.
